General:
The MX122 was recently replaced with the MX123 ($9,000) which is 8K capable. Other than the video processing the units are very similar.

This came from a single owner who is super gentle and mindful with his gear.

This is a complete kit including the original McIntosh shipping carton, manual, remote, and the room calibration mic with stand.

• The MX122 can serve as the brain center for an advanced home theater system for years to come.
• Supports object-based 3D audio formats including Dolby® Atmos, and will be upgradable for DTS:XTM and Auro-3D®. Popular legacy surround sound formats are also supported.
• Plays 4K Ultra HD native sources as well as upconverting lower resolutions to 4K Ultra HD for the best possible picture quality. Compatible with 3D video.
• All HDMI inputs and outputs are HDCP 2.2 and support High Dynamic Range (HDR), 4K Ultra HD at 50/60Hz, 4:4:4 color, Rec. 2020 and 3D video pass-through.
• Audyssey MultEQ® XT32 calibrates the MX122 to your room’s unique acoustical properties, letting it deliver the clearest and most balanced sound possible.
• Ample amount of connections to connect your existing and future HD, 4K Ultra HD and audio sources.
• Wi-Fi, Bluetooth and AirPlay® provide further connection choices.
Interfaces to popular streaming services1 including Pandora®, SiriusXM® and Spotify®.

Testing Process:

We start with a visual inspection of all internal components to make sure that there are no signs of heat stress or damage. Capacitors are checked for telltale signs of predictive failure including bulging, shrunken wrappers, or physical leakage. We also inspect the PCB’s for discoloration from resistors or transistors that may have been running hot. On vintage units we often spot check select capacitors for value and ESR.

When we first power on a preamplifier we connect its RCA output to a Sencore PA81 Power Analyzer which simulates real world loading conditions and gives us an oscilloscope interface. The first order of business is checking that the volume control works smoothly throughout its entire range with acceptable channel balance. This is accomplished by feeding a 1KHz sine wave into one of the preamp’s line level inputs while monitoring the preamp’s output on an oscilloscope. We then switch to a 1KHz square wave to test the tone controls, loudness function, and filters where applicable. During this step we are watching for equal alteration of the test signal by both channels. This also helps us identify dirty controls that will need treatment. Once the basic line stage functions are verified, we test each input individually. This is especially important for devices that use relays to select their sources. If the preamp is equipped with a phono stage we test that as well. We use an inverse RIAA filter which allows us to feed a reference test signal into the phono input with the proper RIAA equalization and level. A square wave or sine sweep is used to verify that the device’s phono stage is faithfully reproducing the RIAA curve. If the preamp under test has balanced inputs and/or outputs these are tested as well.

We finish up our bench testing with a listening test with our bench amplifier and reference speakers. During this test we check for hum or hiss that may not have shown up in earlier testing. We also check that all of the tone controls and filters perform as expected. If the preamplifier has remote control functions these are also tested. Preamps with tube circuits or complicated power supply topologies are connected at our long term test rig for extended stress testing under real world conditions.
